Patent JP-H0331700-A (JP)
Title: Opening mechanism for door
Inventor: HAYASHI MIKIO
IPC: F42B19/38
Filed: 1989-06-29
Abstract: PURPOSE:To compact and reduce the weight as well as the range of steps of the outer periphery of a submarine sailing body to improve the performance of the same by a method wherein the submarine sailing body is provided with an engaging member, released from the main body of the submarine sailing body together with a door when the pressure of a floating bag has arrived at a given pressure. CONSTITUTION:When a floating bag 6 is inflated by a gas pressure, a door is pushed up from the inside thereof and an engaging member 5 is released from tb USE:he main body 1 of a submarine sailing body. Usually, a cylindrical part in a plug 8 is contacted with the cylindrical part 9c of a retaining piece 9 and a part near the tip end of a lip 8a is contacted with a steep taper 9d whereby the door 2 is fixed. When the door 2 is pushed up continuously and the displacement thereof is increased, a reaction force is stagnated when the tip end of the lip 8A is approached to the final part of the taper 9d, then, the reaction force is reduced quickly when the displacement is increased further and the tip end has passed the maximum point of the reaction force. When the lip 8A has arrived at the cylindrical part 9c, only the resistance force of friction is applied and, thereafter, the reaction force becomes zero. Accordingly, when the opening pressure of the objective door 2 is set so as to apply a force, stronger than the maximum point of the reaction force, on the plug 8, the plug 8 is released from the retaining piece 8 and the door 2 may be released from the main body 1 of the submarine sailing body.

IPC: B29B7/00
Filed: 1981-10-15
Abstract: PURPOSE:To obtain a small-scale press apparatus whose mold can be readily replaced, by including a mold into which a casting material is injected and a chamber that contains the mold under a vacuum or pressure, and resiliently connecting the split sections of the mold with the split sections of the chamber. CONSTITUTION:The chamber 12 that is now in the open state is closed by forcing a movable plate 15B to the left by a press apparatus 16. Then the mold 11 is also closed at the same time since the mold 11 and the chamber 12 are connected by resilient members 18, and the split sections 11A, 11B of the mold 11 are resiliently engaged under the suitable resilient force of the resilient members 18 to complete the assembling of the mold. When it is required to disassemble the mold 11, the split section 12B of the chamber 12 is moved to the right by the press apparatus 16, and at the same time the mold 11 is released. The replacement of the mold 11 can be readily effected as the mold 11 is not fixed to the chamber 12.

IPC: C21D9/02
Filed: 1978-12-29
Abstract: PURPOSE:To enhance the operation rate of annealing work and the thermal efficiency of annealing by electrifying a wound coil spring to anneal it during conveyance. CONSTITUTION:Electrifying materials 2 are set at the middle of the opposite edges of parallel guide rails 1 leaving such a space that coil spring S to be annealed can not pass. Endless running body 3 whose carrier side faces to the tails of rails 1 from the heads is placed between rails 1, and body 3 is provided with kickers 4 conveying spring S while in contact with an end of spring S.

Abstract: PURPOSE:To provide a printing machine paper stack bed wherein sheet paper can be always surely conveyed and fed, even when the sheet paper is decreased by a paper feed, and further the initial reference position in accordance with thickness of the sheet paper can be easily recognized and set. CONSTITUTION:A thickness side surface of separated sheet paper 10, floated by air from a blow nozzle 6, is detected by two reflecting sensors 21, 22. Since a floated length is different between the cases of thick (A) and thin (B) thickness of the sheet paper, the paper thickness is discriminated in accordance with a light receiving quantity of both the sensors, and an optimum separation condition value corresponding to this discriminated thickness can be recognized. Thereafter, a stack bed, loaded with a sheet paper bundle 2, is lifted so that the light receiving quantity from the sensor 21 is always obtained equal to the optimum separation condition value.
